Shard Awakening (The Shard Legacy Book 1) by Martin Knaggs
Two children are born carrying something humanity was never meant to control.
The Shard is an ancient alien intelligence, long mistaken for a disease, now awakening inside them. Governments see weapons. Empires see leverage. An enemy older than recorded history sees unfinished business.
As the twins grow, so does the danger, not just to them, but to an entire galaxy balanced on the edge of collapse. Protecting them may cost everything. Letting them fall could end everything.
Shard Awakening is the first book in an epic science-fiction saga about family, sacrifice, and what happens when power chooses the wrong hosts.
